Gartner's interview process has five possible stages before the outcome: the application, a phone interview, virtual or in-person interviews, an assessment or project for some roles, and a case study presentation for some roles. Gartner says on its interview process page that the process differs by role.
Everything below comes from Gartner's own careers site, linked as we go. Where a detail comes from one Gartner recruiter's account rather than official guidance, we say so.

What is the Gartner interview process?
You apply online, speak to a recruiter on the phone, then interview with the team, with an assessment, project or case study for some roles. Gartner says: "Your interview starts with your application."
The application
Apply through the Jobs section of jobs.gartner.com, filtering by function and location, and create a profile. Gartner reviews each application for "suitability to the role" you applied for. If you're not ready to apply, you can join Gartner's Talent Community and get matching jobs by newsletter.
Gartner may or may not pay interview expenses, depending on the position and country. Check the job description or ask your recruiter once you're invited.

What happens in the Gartner phone interview?
A recruiter calls you. A Gartner sales recruiter describes it on the careers blog as "usually an informal conversation" that is "usually very brief", with the main goal of understanding what motivates you and what you want from your career. If another role suits you better, the recruiter may say so.
Her tips: prepare questions about the role and team, be concise, take the call somewhere quiet with good signal, know what you want, and research Gartner's business model, culture and values.
A 2018 post on Gartner's careers blog, profiling a recruiting coordinator, says these phone interviews usually take 30 to 60 minutes with a sourcer or recruiter. Treat that as one 2018 account.
What happens in the Gartner team interviews?
After the phone interview, Gartner invites some candidates to a virtual or in-person interview, which can be one-on-one or a panel. Gartner uses this stage for you "to learn more about the role and the team" as well as for the team to assess you.
Gartner uses behavioural-based interviewing: questions ask for a specific example from your past work or study, not a hypothetical. Its advice is to answer in STAR form (situation, task, action, result), and: "We are a very data-driven company, so it's always great to speak to your impact as you describe your results." Our STAR method guide shows how to structure these answers.
The same 2018 post says that "Gartner is big on trait-based interviewing", and describes the coordinator's final interview with a department leader.
Does Gartner have an assessment or case study?
For some roles, yes. Gartner says you may need to complete an assessment or project that is relevant to the role, to help it "develop a better understanding of your skills". You may also be asked to present a case study; Gartner says your answers "should be clearly thought out and showcase your creativity".
Gartner doesn't publish which roles have an assessment, what it contains or how case studies are scored. Your recruiter is the best source for what to expect.
For a case study presentation:
- Lead with your recommendation, then give the reasons.
- Use numbers where you can, since Gartner calls itself data-driven.
- State your assumptions so the panel can follow your reasoning.
- Leave time for questions, and treat pushback as part of the conversation.
How long does the Gartner hiring process take?
Gartner doesn't publish an end-to-end timeline. It says that after your interview it aims to "get back to you within a week" with the outcome, and your recruiter will tell you if it will take longer.
What happens after the Gartner interviews?
Gartner's official pages don't describe the offer stage. The 2018 recruiter-blog post profiling a recruiting coordinator describes her receiving feedback within a couple of days of her final interview, a verbal offer, then an emailed offer letter conditional on a background check that took five to seven business days. Your experience may differ.
If you're not successful, Gartner says you can reapply. It will consider the new application on its own merits.
Common Gartner interview questions and how to answer them
Gartner's recruiters have published three of their favourite questions (questions 1 to 3 below). The rest follow Gartner's behavioural interviewing guidance and what it says it looks for.
1. Why did you choose to apply for this role?
A Gartner recruiter says this shows whether you have clear career plans and passion for the role. Explain what motivates you, where this role fits in your plans and why Gartner in particular.
2. Tell me about a time you learned something on your own. What steps did you take?
A Gartner recruiter says this tests a self-starter mindset. Pick something you chose to learn, not something a boss or professor asked for, and walk through your steps.
3. How do you prioritise your day?
A Gartner recruiter uses this to test time management and whether you can tell urgent tasks from important ones. Describe your real method with an example of a day when priorities clashed.
4. Tell me about a result you're proud of.
Gartner asks you to "speak to your impact". Give the number: revenue, time saved, clients kept, grades improved. Use Gartner's "Power of 3": three clear actions that led to the result.
5. Tell me about a time something didn't work out.
Gartner's behavioural interviewing tips say to be ready to discuss an unsuccessful outcome, what you did about it and what you'd do differently. Recruiters look for how well you use feedback.
6. What could you have done differently?
Gartner lists this as a follow-up interviewers use. Have a specific answer for every story you prepare.
7. Tell me about a time you worked with a team to win.
Gartner says it hires people "who collaborate and win as a team". Show your part and the team's result.
8. Tell me about a goal you set yourself and reached.
Gartner says how far you go "is driven by your passion and performance", and recruiters look for drive. Choose a stretching goal and show how you tracked progress.
9. How would you build a relationship with a senior executive?
Gartner says its sales roles act as "a strategic partner with C-level and senior executives". For sales and client services roles, give an example of earning trust with someone senior, and how you prepared.
10. Tell me about a time you used data to make a decision.
Gartner calls itself very data-driven. Explain what data you used, what it told you and what you decided.
11. What do you know about Gartner's business?
Gartner's phone interview tips tell you to research its business model, then connect it to your role.
12. What questions do you have for us?
Gartner says "This is your chance to interview us!" Prepare questions about the team, how success is measured and how people grow.
Our list of behavioural interview questions has a bigger bank to practise on.
How to prepare for the Gartner interview process

Practising realistic work tasks
Interviews reward prepared stories. Assessments, projects and case studies reward judgement, and that improves with practice on realistic tasks. Cohesyve, which publishes this guide, runs practice job simulations for your role, with a scored report on where you lost marks. It isn't affiliated with Gartner and doesn't use Gartner's assessments or questions.
